Nov. 11, 195s United States Patent C) RADIATORS Eric Sigfrid Persson, Ribershus, Malmo, Sweden Application September 14, 1956, Serial No. 609,874

Claims priority, application Sweden September 19, 1955 4 Claims. (Cl. 257-136) The present invention refers to heat radiators in the form of a heating pipe coil and a heat-yielding front member removably arranged on said pipe coil.-

The object of the invention is primarily to form a radiator of said type with a holding device for the front member in such a manner, that the latter can be readily suspended from the heating coil and removed again from the same, whereby the heating coil as Well as any cocks on the same become accessible for cleaning and repairs.

Another object of the invention is to provide a radiator of the type referred to above, with a holding device for the front member, said device not only facilitating convenient arrangement and removal of the front member but also forming a reinforcement for the front member, so that the latter can be made from comparatively thin sheet-metal. Y

A further object of the invention is to provide a construction of a radiator front member to permit the latter to be manufactured according to simple methods.

A substantial distinguishing feature of the invention resides, above all, in the provision of holder bars or rods for the suspension of the front member, said holder bars being each per se thrust in an endwise fashion into slots in the front member while being provided with a portion adapted to clasp about a portion of the heating'coil. By the fact that the holder bars are displaceable endwise in slots in the radiator front member, it will be possible readily to arrange them in their places and also to mount the front member on the heating coil in difcultly accessible places. Furthermore, the holder bars generally facilitate the arrangement of the radiator front member on and its removal from the heating coil.

The invention also comprises a radiator front member intended for radiators of the nature set forth, and said front member may consist of wave-shaped sheetmetal having the wave crests on one side thereof formed with at least one row of recesses or cuts, which together form a track or channel for a holder bar. In mounted position, the holder bar or bars will cross the waves of the front member and will be visible through the recesses on the fore side of the front member, which brings about a certain decorative effect.

A few examples of applying the invention are illustrated in the accompanying drawing. Fig. l is a vertical elevation showing the radiator mounted underneath a window, and Fig. 2 is a corresponding vertical section. Fig. 3 is a portion of the vertical section according to Fig. 2 on a larger scale, and Fig. 4 is a corresponding vertical elevation of the front member on the same scale as that of Fig. 3. Fig. 5 shows a horizontal sectional view of the portion of the radiator represented in Figs. 3-4 and on vthe same scale as in the latter gures. Fig. 6 is a vertical section showing a modiiied construction in the same way as Fig. 3.

According to the drawing, the radiator consists of a heating pipe coil 10 with superimposed horizontal pipe portions and a heat-yielding front member 1 suspended 2,859,947 Patented Nov. 11, 1958 2 from said pipe portions. The front member consists of a sheet of wave-shaped -metal supported by the heating coil by means of holder bars or the like 12. The construction shown comprises two such bars.

The holder bar is of a cross section, which may be regarded as being composed of a broadly T-shaped member 14 and of a hook 16, Fig. 3. The T-shaped member is adapted to tit into a correspondingly shaped channel 18 in the front member. This channel is provided with slots or recesses 18 in the wave crests 20 of the front plate facing the heating coil. The slots 18 lying abreast one another in a row form together the channel 18, into which the part or fillet of the T-shaped cross section is fitted when the bar 12 is thrust endwise therein. Through the slots 18 the holder rod becomes partly visible on the fore side of the front plate, as will appear from Fig. 4.

The slots 18 may be readily produced by a simple mechanical operation, for instance by milling.

The part 16 of the holder bar, which is of an arcuate cross section, embraces in the suspended position of the radiator front member a horizontal pipe portion of the heating coil for the greatest possible portion of the length thereof and over a substantial portion of its circumference, whereby the heat transmission from the pipe to the front member is facilitated. The heattransmitting surface may be further increased by the holder rod being also provided with an arcuate portion embracing the pipe of the heating coil from the lower side, as in the modification shown in Fig. 6, where the pipe is embraced about the major portion of its circumference.

The radiator is mounted in a wall section within a frame 24 underneath a window 26 arranged therein and gives a favourable decorative effect by reason of the corrugated shape of the front member and the holder Fr"ice 4 bars visible through the recesses in the front member.

The holder bars 12 assist in reinforcing the front member, which latter may thus be made from thin sheetmetal, whereby a certain saving of material is attained. They facilitate the mounting of the radiator front member not only by permitting of being hooked onto the heating coil but also by being displaceable along the channels in the same, so that the sheet-metal member may also be adjusted into the desired position in difcultly accessible places.

What I claimis:

1. A radiator comprising a heating element and a radiating front member suspended from the heating element by supplementary holding bars thrust endwise into front slots in the front member and provided with a portion embracing portions of the heating element to conduct heat from said element to the radiating member.

2. A radiator comprising a heating coil, a radiating front member of sheet metal, and bars, the latter having a cross section composed of a broadly T-shaped portion and a hook, and the sheet metal member being provided with slots adapted to receive the T-shaped portion of the bars to enable suspension of said sheet metal member on the heating coil by means of said bars.

3. A radiator comprising a heating coil, a radiating front member of wave-shaped or corrugated sheet metal providedwith a straight row of slots traversing the crests of the waves, and holding bars having a cross section composed of a T-shaped portion and a hookshaped portion, said bars being thrust endwise with said T-shaped portion into said slots in the transverse direction of the corrugations of the front member to connect the front member with the heating coil when suspended therefrom.

4. A front member for vradiators comprising a waveshaped or corrugated she'et met'al element having at least one row of slots vtraversing the crests ofA the corrugations to form a channel for ra holding element; said holding element extending transversely of the corrugatio'ns and comprising a heat conducting member for engaging the radiator to transfer heat therefrom to said metal element.
